Buy Viagra is the well-known brand name for sildenafil citrate, a medicine primarily used to treat erectile dysfunction (ED) in men. It was first approved in the late 1990s and has since become one of the most widely prescribed drugs in its category.saxenda-weight-loss

🔬 How It Works

• Viagra belongs to a class of medicines called PDE5 inhibitors.

• Normally, sexual stimulation triggers the release of nitric oxide, which increases a chemical called cGMP that relaxes smooth muscles in the penis, allowing more blood to flow in.

• PDE5 (phosphodiesterase type 5) breaks down cGMP.

• By blocking PDE5, Viagra helps maintain higher cGMP levels, leading to stronger and longer-lasting erections.

• Importantly: Viagra only works with sexual stimulation; it does not cause automatic arousal.female-viagra-100mg

💊 Medical Uses

• Erectile dysfunction (ED): Difficulty achieving or maintaining an erection.

• Pulmonary arterial hypertension (PAH): In lower doses, sildenafil is also marketed under other names (e.g., Revatio) to lower blood pressure in the lungs.levitra-20mg

🕒 How to Take It

• Usually taken 30–60 minutes before sexual activity, but can work up to 4 hours after dosing.

• Typical starting dose: 50 mg (can be adjusted to 25 mg or 100 mg depending on response and tolerance).

• Not more than once daily.

• Works best on an empty stomach (food, especially high-fat meals, can delay its effect).cenforce-100
